Door



Patented Apr. 12, 1932 TATES UNITE MAX BRISKIN, OF CHICAGO, ILLINOIS DOOR Application filed May 11,

This invention relates to doors, and in certa1n respects 1s 1n the nature of. an lmprovement upon the door shown and descrlbed 1n my application for patent thereon filed November 8, 1930, under Serial No. 494,323,

of which this tinuation.

This invention has reference more particularly to sheet metal door assemblies which application is in part a conembody their own hinges, and one of the objects of the inventin is to stiffen and strengthen the door, as well as the panel or other wall upon which the door is hung. Another object is to provide improved automatic means for holding the door closed as well as in a plurality of openpositions. Another object is to provide self-contained means whereby the door may be accurately positioned with respect to the door opening in the wall or other panel upon which it is hung so as to eliminate the necessity of a jig for accurately locating the door.

With these and other objects and advantages in view, this invention consists in the several novel features hereinafter, fully set forth and claimed. 7

The invention is clearly illustrated, in the drawings accompanying this specification in which-* Figure l is a side elevationof a fragment of a wall or panel, looking at the rear side thereof, upon which is hung a door embodying a simple form of the presentinvention; 7

i 2 is a vertical cross section taken on the line 2-2 of Fig. 1, showing certain parts broken away to reveal other parts which would be otherwise hidden from view;

Fig. 3 is a horizontal section taken on the line 33 of Fig. 1; and

Fig. 4 is a fragmental side elevation of the wall and the hinge plate which forms part of the device and connects the door withthe along portions of thetop and bottom there- 1931. Serial No. 536,439.

of the flange '8 is bent over the opening to form a flange 8 whichlies parallel with the panel or wall 6 and serves as a positive stop for the 'door in its closed position. The

corners of the opening and the flanges at said T corners are rounded off, as shown, to improve the appearance of the device.

The door 9-is in the form of arectangular sheet metal panel or plate having a marginal flange 10 which is turned in towards the flange 8 and forms a reinforcement for the door. The corners of the door are also rounded oif,as shown, anda very. slight clearance space is left between the door and edge of the door opening A knob or other handle 11 is provided upon thedoorby which it may be opened and closed. Spot welded or otherwise rigidly secured to the inner face of the panel or wall 6, at the hinged side of the door, is a hinge'plate 12 of rectangular form extending parallel with one side edge of the door. The hinge plate is formed with a longitudinally extending flange 24: along the edge adjacent the door. and said flange serves to materially stiffen the panel or wall 6' as well as to reinforce and stiffen the hinge plate. The flange 24 also serves to guide the hereinafter described door holding spring 19. The ends of the H hinge plate 12 are bent up to form hinge ears 13 that cooperate with hinge ears'o n the door, as will be presently explained.

The side of the door 9 adjacent the hinge plate is formedwith an arcuate flange 15 which extends from the marginal side flange .10 of the door and terminates in-a U-bend 15 The ends of the arcuate flange 15 are bent up to provide end flanges 17 that terminate in ears 18 which are connected to the hinge ears 13 of the hinge plate 12 by rivets or the like 14:. i

Anchored upon the hinge plate 12 is the spring 19 which serves to hold the door closed as well as in a plurality of open positions. The spring is bent up from a piece of spring wire and comprises a middle section 20 from whichextends two U-bends 20 that terminate in arms22 which pass through slots 23 formed inthe flange 24 of the hinge plate andengage in notched'slots 25 formedv in the arcuate portion 15 of the door. The arms 22 are adapted to engage in any of the notches 27 of the slots 25 to thereby hold the door closed or in any of several selected positions. With this form of spring greater resiliency for the arms 22 is obtained.

The arms 22 are capable of movement in a plane parallel with the plane of the door and wall and are urged into the notches of the notched slots 25. As shown, the arms are guided in the slots 23 for movement into and out of the notches of the notched slots 25 and are held against lateral movement in a direction transversely of the panel or Wall 6 by the side edges of said slots 23, so that when engaged in any one of the notches 27 the arms will hold the door in the position controlled by the notches. The middle section 20 of the spring is held in place on the hinge plate 12 by a tongue 21 struck up from the hinge plate and bent over said middle sec tion of the spring.

The hinged together door and hinge plate and the spring are assembled as a unit ready for installation upon a panel or wall. In order to accurately space the door in the door opening in the panel without the use of a or other mechanism, cars 28 are formed upon the ends of the hinge plate 12 and have curved edges 29 which correspond with and conform to the outer curved faces of the flange 8 of the panel or wall, whereby when the ears 28 are placed in register with the curved faces of the flange 8 (see 4) the entire door device is accurately positioned, with the door 9 itself properly spaced in the door opening. Thenthus properly located, the hinge plate is spot welded to the panel or wall 6 as at 30, thereby rigidly fastening the door assembly to the panel or wall.

It vill be observed that the arcuate portion 15 and hinge plate 12 are somewhat shorter than the door 9 itself. The purpose of this is to permit the formation of the rounded corners on the door having relatively long radii.

The present door device is particularly useful in controlling the ventilating openings of hoods for automobile engine's, although it is to be understood that its use is not to be limited thereto. Moreover, the door and hinge plate form two leaves of a hinge and when provided with the spring stop means, above described, is capable of use in connection with various types of closures for holding them in closed position as well as several selected open positions.
